Are you guys talking about a high-pitched or chirpy vibration sound? I am getting it in my V6 WK2 as well, and it's really hard to pinpoint. It does seem like it's from the left front engine area or dash area. It only occurs when I am accelerating, especially at slower speeds (rarely hear on highway). I have a build date in May, so I don't think I have the bracket in the steering area issue.

That sure sounds like the sound...mine was a May build date as well. Please get your rattle registered with Jeep ASAP. My dealership took some 2014's out that were on the lot and some made the sound and some did not, made no difference V-8 or V-6 or model style. It sure sounds like a sound shield somewhere but no one can find it. You know it will be something very small and dumb when it is discovered. Please register so it really gets onto the radar at Star Customer Service so we can get resolution. Thanks

I have removed every darn label I can find in the engine compartment and the steering bracket has been checked/removed at the dealership. I filled up with prem gas last night and the noise is still as it was so it is not a ping atleast the way I know pings. Starts in at like 18 peaks at 32 and then either goes away or you just can not hear it. Can not hear it with the window down. Dealership at the advise of Jeep thru the shifter into neutral at 35 MPH no difference, sound still there. I have seen the sound described (here I think) as the sound coming from a kids bike bell rattling as you go down the road. Does seem to come form the left front section of the engine compartment but not in the dash area. Dealership is awaiting word from Star but nothing has come yet. For a moment or two they suspected perhaps the transmission but throwing the vehicle into neutral and still the noise kind of stopped them going in that direction. Only accelerating and vehicle actually moving makes the sound.... It does seem to be getting louder so perhaps that is a good thing.....come on folks I know you must have some ideas! Thanks, Ron

When you originally said it only happens in 2nd or 3rd gear, those are the main acceleration gears so I though maybe motor mount deflecting (due to torque) along with a heat shield making momentary contact... but the dealer test to put it into neutral pretty much takes that out of the equation.

Since it does it "coasting", it has to be front half shafts/wheel bearing/brake rotor dust shield or maybe even a defective front differential.

I will try mine some more tonight, there is no question you hear it when you step on it, the dealership said they heard it when in neutral and coasting at 30MPH, I am not sure I would agree completely. While I realize sounds/rattles sound different to different people this one really seems like the same noise to all of us?

As the owner of the dealership said... most people would most likely not hear the noise but to the rest of us (including him) it would drive you insane everytime you start the car and step on the accelerator. I do hope we get some support and help with this issue soon. Thanks.

Going to be bringing it in to the dealer tomorrow to take a look (or a listen really) at this. Dreading the visit, hoping I don't get the bull@#$% line that they: 1) Can't hear anything or 2) Try and say that the noise is "normal".

Best of luck! Jeep corporate trouble shooter is coming again to look at the car after the 4th holiday. I wish is was going to be sooner but at least they are giving the situation some attention and for that I say thanks. Make sure the dealer gets yours registered with Star if they can not find the cause
